One source told us, “Guests were asked to fly into Denver, where they would be driven around three hours to the wedding location, but nobody knew where it was going to be.” A rep for Allison Williams confirmed the couple were married Saturday night.

The Brush Creek Ranch, a luxury dude ranch situated on 30,000 acres of spectacular Rocky Mountain wilderness, has been voted the No.1 resort in the US by Conde Nast Traveler.

It offers private wedding parties for up to 150 people which can take place outdoors overlooking the scenery or inside rustic lodges. Guests are offered a variety of outdoor activities including horseback riding, trail adventures, fly fishing and shooting.

A favorite with celebrities, the ranch was also the venue for CBS news anchor Chris Wragge’s wedding to Sarah Siciliano in July.
